IPC: C07C45/65
Filed: 2000-12-22
Abstract: Processes for the preparation of optically active enones (4) and (7) from starting material (1). R<SP>2</SP> and R<SP>3</SP> are the same or different and are each a hydroxyl protecting group or together form a hydroxyl protecting group, R<SP>5</SP> is hydrogen, alkyl or phenyl and R<SP>1</SP> and R<SP>4</SP> are different to each other and are each a hydroxyl protecting group. The processes consist of removing protecting group R<SP>1</SP>, oxidising the resulting free hydroxyl group and then removing the group OR<SP>4</SP> with formation of a C-C double bond to give enone (4) and removing protecting group R<SP>4</SP>, oxidising the resulting free hydroxyl group and then removing the group OR<SP>1</SP> with formation of a C-C double bond to give enone (7).

Title: Reducing sensor temperature in magnetoresistive recording heads
Inventor: MURDOCK EDWARD S
IPC: G11B5/40
Filed: 1999-07-21
Abstract: A method and apparatus for dissipating heat generated in a sensor element of a vertical magnetoresistive recording head or flux guide magnetoresistive recording head having a recess formed in the lower and/or upper magnetic shields for enhancing efficiency during reading data from a magnetic medium. Heat is dissipated through a non-magnetic metal filler layer (10, 12) formed in the shield recesses (140) between an upper (2) or lower (6) metal shield and a sensor element (4) comprising a magnetoresistive head structure. The metal filler (10, 12) must be non-magnetic, must avoid an electrical short between the sensor element and the upper (2) or lower (6) magnetic shield, and must be compatible with the adjacent shield in terms of adhesion thereto and the thermal expansion coefficient thereof. An insulator layer (11, 20) comprising an electrical insulator is formed between the sensor element (4) and the metal filler (10, 12) to insure electrical insulation. The metal filler (10, 12) acts as a thermal path from the sensor element (4) to the metal shields (2, 6).

Inventor: RYDER JOHN LEONARD
IPC: G06T7/00
Filed: 2001-03-01
Abstract: An automatic inspection method for inspecting a web 14 having a regular pattern of discrete areas thereon, comprises the steps of scanning a portion of the web with a camera 10 to produce a digital image of the scanned web portion, and converting the digital image into binary format. The number of discrete areas portrayed in the binary format image are counted, and the binary format image is filtered to identify any deviation from an ideal binary format image. The number of pixels comprising the deviation from the ideal image are counted to yield a grading value, and the discrete area count and grading value of the image are compared with respective pre-set limits for determining the quality of the pattern.

Inventor: HUANG SUJIAN
IPC: E21B44/00
Filed: 2001-10-11
Abstract: The dynamic behaviour of at least a drill bit and a section of drill string are determined using a numerical model. Interactions between the drill bit, drill string, rock formation, drilling fluid and the above surface assembly are all incorporated, allowing the method to be used to design and optimise drilling systems via an iterative approach. The model output may be converted into a visual representation of the drilling process.

Title: Retaining broken drill in rock drilling apparatus
Inventor: GREEN CHRISTOPHER J
IPC: E21B17/07
Filed: 2002-03-01
Abstract: A rock drilling apparatus includes a drill string terminating in a drill chuck (32) and a drill bit (16) Fig 1 detachably fitted into the drill chuck, the drill bit having a shank (18) received in the drill chuck, the drill chuck (32) and the drill bit shank (18) having complementary splines and grooves allowing rotation or movement of the drill chuck to be transmitted to the drill bit whilst allowing limited longitudinal movement of the drill chuck relative to the drill bit. The drill bit has a drill head (22) at its lower end which is of greater diameter than said shank, said head having a part (26) above that lower end and below the splined region. The part (26) and the surrounding part (38) of the chuck provides respective parts of a bayonet connection arrangement which is substantially unstressed in normal operation of the drill, the arrangement being such that, in normal operation, the weight of the drill string and the weight of the drill bit during lifting of the drill string are supported by complementary formations on the drill shank and the chuck, whereas the bayonet connection arrangement prevents complete detachment of the drill bit head from the chuck in the event of a fracture of the bit above the drill head.

Patent GB-2388940-A (GB)
Title: Method and apparatus for the correction or improvement of word usage
Inventor: WHITELOCK PETER JOHN
IPC: G06F17/27
Filed: 2002-05-22
Abstract: A database is provided containing links between words with likelihood values associated with the links providing a measure of the likelihood of such links being correct or idiomatic. The likelihood values are based on the frequencies of occurrence of the links obtained by analysing a large body of text, for example produced by native speakers of the language. In order to check a section of text for possible erroneous or unnatural usage of one or more words of the section, the text is first analysed to establish links between its words. The likelihood of the links in the analysed text is determined from the database. A plausibility value is computed for each word in the analysed text, by combining the likelihood values for the links in which that word occurs. Words are used to index another database containing sets of words which are confusable with the index word. Each of the confusable words is selected in turn and substituted in the links of the index word. The likelihood values for these new links are determined and a plausibility value for the confusable word is computed. In an error-correcting embodiment, confusables are tried for those words whose plausibility falls below a threshold, and confusables which improve plausibility are reported to the user. In a context-sensitive thesaurus embodiment, confusables may be tried for all words, and those for which the plausibility value exceeds a second threshold may be reported.
